'Awake' series finale: Which one of Michael Britten's realities is all a dream?

"Awake" creator
Kyle Killen and star
Jason Isaacs have both said all along that one of Michael Britten's realities is a dream -- either the one in which his wife (
Laura Allen) survived a car accident but his son (
Dylan Minnette) died or the one in which the reverse is true. And Thursday (May 24), fans will hopefully get a satisfying answer to the single-season series' mystery during the finale airing at 10 p.m. on NBC.

"We left nothing off the table,"
Isaacs tells EW.com. "It feels like a real ending. Nobody who's watched the show is going to come up and want their money back in the street."

Anyone expecting a definitive answer to "Which one of these realities is real?" may be wanting their viewing time back, though, as Killen hints that we probably won't get one.

"The episode certainly feeds one of those theories," Killen says. "When we wrote the episode, we didn't know it would be the end of the series, so it would have been impossible to answer that question ... But you don't need every question answered. I think what you need is something that feels like an emotional resolve, and I think it definitely offers that. It's a really satisfying conclusion, and I think it will be a satisfying way to leave the show."

What do you think will be revealed? Which of Britten's realities do you think is the real deal?
